What does it mean if a signal turns green while you are stopped at an intersection?

Answer: B — You may proceed when it is safe to do so

When a signal turns green while you are stopped at an intersection, it indicates that you are allowed to proceed through the intersection, provided it is safe to do so. The green light signals that vehicles may move in the direction indicated by the light, which is typically straight ahead or in the direction of a turn permitted by any accompanying signals or signs. It's important to assess the intersection for any oncoming traffic, pedestrians crossing, or obstacles that may affect your safety before moving forward. While the green light gives the authority to go, the responsibility for safe passage lies with the driver. Therefore, ensuring that conditions are clear and safe before proceeding is a crucial aspect of driving protocol. The other choices suggest either remaining stopped or conditions that do not align with the meaning of a green light, which does not restrict movement as long as it's safe to proceed.
